Follow-up Comment #5, bug #32502 (project octave): Still I'm not sure that Octave do the things right. Once again here is the code (from Octave): c = conj (x' * x / (n - 1)); Here we see a double complex conjugation. First operator' do conjugation, and after it there is an explicit call to conj. In mathematical notation we do the following: H H / X X C = |--------| N-1 / So I think that the extra call to conj is erroneous, am I right? _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?32502> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
